`Application filed October 8, 1920. Seria] No. 415,581.

To all whom t may concern.' y

Be it known that I, THOMAS BENsoN, a citizen of the United States,residing at Washington, in the District of Columbia, have invented newand useful Improvements in Cord Tighteners for Awning Operators,

of which the following is a specification.

The objeotof thisinvention is to provide a cord tightener for awningOperators whereby .theawning may be raised and lowered from theinside ofthe building and without the necessity of the window or the like be` ingopened for the entry of the elements.4

With this and other objects in view as will be more speciiicallyfpointedout in the Afollowing specification and claims, reference.

'willjbehad to the accompanying drawing forming a part of thisspecification. and wherein like numerals of reference designatecorresponding parts throughout the several views, in which a Fig. 1, isan elevation of a fragment of a window with awning lowered viewed fromthe inside of the building,

Fig. 2 is a vertical transverse sectional view thereof,

Fig. 3 is a front elevation view of the cord tightener,

Fig. 4 is a Side elevation view of Fig. 3,

Fig. 5 is a horizontal Sectional view taken through Fig. 4 on the line 55,

Fig. 6 is a front elevation of a fragment of the window viewed from theinside of the building, and

Fig. 7 is a longitudinal vertical sectional view through the cord guide.

Referring to the drawing, reference numeral 1 denotes the wallof abuilding, in which is set the usual window frame 2, having the usualguide strips 3, 4 and 5. Between the guide strips 3 and 4 slides thelower window sash 6, while between the .guide strips 4 and 5 slides theupper Sash 7.

lhe strip 3 extends down the sides of the sash and across the topthereof, and in a like manner extend the other guide strips 4 and 5. Theawning 8 is attached in the usual manner as by fastenings 9 to thebuilding and has the usual operating cord 10 passing through the usualscrew eyes 11. lnstead of the operating cord extending down the outsidewall of the building and there fastened, the Same passes from said eyes11 through a tubular guide 12, thence down the inner face of the windowframing where it is adjustably attached to a cord tightener 14 which isslidably adjustably mounted on?.

a ratchet rod 15, Secured at its Opposite ends to .the window framing.The guide Strip sections 3 at the top and one side of the window framingare out out for the accommodation of the cord guido.'`

member 12, as illustrated in Fig. 6, and similarly are the guide strips4 and l5` cut away. This permit-S the cord guide member to be placed inthe extremecorner of the window frame and there secured byscrewswl the@Vheads of which are aermitted to pass through the outer wall of the cordguide due to the enlargedv openings 17, and said openings 17 receive thescrew driver inplacing these screws. In Fig. 6, it will further benotedI that the upper sash 7 (and the lowerfsash also if desired) isnotched or cutout 'as at 18 in Yone corner for the accommodation'of thecord guide `member,and by this conand between the guide strips 4yand; 5vat the top, no openin is presented for entrance of struction, when theupper sash is fully raised@ and easy passage of the awning operating n'cord 10 through the cord guide member 12, said member is equipped at itsfront end with a roller 20, in the plane of the lower wall of the guidemember and journaled between two downwardly extending ears struck fromthe body of said cord. guide member. Also, at its rear end, otherrollers 22 are provided in the plane of the side walls of the cord guidemember and journaled between extensions 23 of said cord guide member.

The cord tightener 14 comprises two sections 24, 25 secured together bytransverse bolts 26. Upon one of the sections, in the drawing, section24, is mounted a cleat 27 to which the awning operating cord 10 issecured; and in the lower end of one of these sections, shown in thedrawing as Section 24, is insertedv a screw eye 28 which serves as ahandle for adjusting the cord tightener on the rod 15. At intervals, therod 15 has ratchet teeth 29, to hold the cord tightener in adjustedposition, through the medium of a pawl 3() pivoted to the other saidsection 25 of the cord tightener. This pawl operates in a recess 31 andis normally en gaged with said rod 15 due to being under the tension ofa spring 32 attached to said pawl and to a screw or pin 33 and locatedwithin a recess 34. When the two section.

24 and 25` are secured together, the inner wall f member 24 closes theopen side of the recesses 3l and 34. Embedded within the sections 24 and25 at both the upper and lower ends are guide lingers 33, the projectingends of .which are L-shaped and facing each other to embrace the ratchetrod 15.

In operation, when it is desired to raise the awning, the cord tighteneris pulled downthe'ratchet rod 15, by releasing the pawl and inserting afinger in the screw eye 28, or thepawlneed not be released since it willride over the ratchet teeth of the rod vand when the awning has beenfullyl raised will enter behind one of the ratchet teeth and retain theawning in raised position. To lower the awning, the pawl 30 isdisengaged from .the ratchet teeth 29 and the cord tightener permittedto ride up the ratchet rod until the awning is fully lowered. Byregulating the position of the cord tightener along the ratchet rod withrespect to the position of the awning before attaching the cord to .thecleat 27, engagement of the pawl with the ratchet teeth at the propertime is insured,

Of course it will be understood that it is the intention to alter andmodify the structural details within the scope of the claims,andto-makesuch other minor changes as will improve and perfect theinvention.

Nhat is Vclaimed as lnew and desired to be secured by Letters Patent isl. A cord tightener, comprising a ratchet rod and a slider mountedthereon, said slid- :n

and a cleat on one of said sections for the L attachment of the cord. Y

2. A cord tightener, comprising a ratchet rod and a slider mountedthereon, said slider comprising two matching sections, each sectionbeing provided with an L-sha-ped finger and the ngers closing about saidrod when the sections are'matched, one of said sections being providedwith a recess, a spring pressed pawl mounted pivotally within saidrecess, the other of said sections closing said recess when the sectionsare matched, a cleat on one of said sections for the attachment of thecord, and a screw eye inserted into the lower end of one of saidsections as a handle.y
